Reflective surfaces are materials that bounce back light, allowing us to see images or colors. Common examples include mirrors, water, and polished metals. These surfaces can create clear reflections, which is why we often use them for personal grooming or artistic purposes. The ability of a surface to reflect light depends on its smoothness and material properties. For instance, a mirror has a highly polished surface that reflects nearly all light, while a rough surface, like sandpaper, scatters light and produces a blurry image. Reflective surfaces play a crucial role in various fields, including photography and architecture.
